An ESOS-aligned heating efficiency programme for UK commercial buildings over 5,000 m². We install patented technology, monitor savings against a verified baseline, and split them with you 50/50. You pay nothing if your bills do not fall. [Book Free Assessment](#book)[See how the programme works ↓](#programme) **Patented UK technology** **40+ year product lifespan** **ESOS-aligned reporting output** **Independently verified savings methodology** The Problem ## Most large commercial buildings are losing 15 to 20% of their heating spend to a problem ESOS audits rarely flag. £30k typical annual heating saving available on buildings over 5,000 m² 15 to 20% typical heating efficiency loss to dissolved gases in untreated wet systems ~20% corresponding reduction in carbon emissions, useful for ESOS and ESG reporting Inside any wet heating system, dissolved nitrogen and oxygen form microbubbles that line the inside of pipes and radiators. They act as insulation. Boilers run harder, heat output drops, bills rise, and the issue rarely surfaces in standard energy assessments because most ESOS audits focus on plant efficiency, not water-side fluid dynamics. The technology we install removes those gases continuously, lifts radiator and emitter surface temperature by 10 to 12 degrees, and protects the system from the corrosion that produces magnetite sludge. Lower bills, longer asset life, and a verified, ESOS-quality savings record for your reporting. The Solution ## VorteXtract: a one-time install that runs for the lifetime of the building. CHEP is an independent operator that deploys VorteXtract, a patented vortex-based heating system optimiser, into the wet heating systems of UK commercial estates, hotels, care homes, and farms. The unit uses your existing circulation pump to spin the heating water into a vortex. The low-pressure zone at the centre draws dissolved gases out of solution. The gases are collected and vented continuously. No moving parts. No consumables. 40+ year working life. Compatible with any wet system: gas, oil, biomass, heat pump, district heating, and hybrid configurations. Once installed, the unit works automatically through every heating season for the lifetime of the asset. Heating cost reduction 15 to 20% (typical) Carbon emissions reduction ~20% (typical) Radiator surface temperature +10 to 12°C Dissolved oxygen post-treatment ~0.2 ppm (inert) System lifespan extension +6 to 7 years Product lifespan 40+ years The Commercial Model ## You take no financial risk. We take all of it. Step 01 ### We fund the installation The unit, the engineer time, the commissioning, the monitoring kit. All paid for by us. There is no invoice from CHEP at install. Step 02 ### We measure the savings Twelve months of pre-install consumption data become your baseline. Post-install consumption is monitored against a degree-day-adjusted forecast. The methodology is auditable. Step 03 ### You share the savings 50% of every verified pound saved goes to you, recurring, for the five-year agreement. If there is no saving, there is no payment. Step 04 ### Renew or we remove it The unit is leased to your building for the five-year term, not sold. At the end of year five you choose: renew the agreement and keep your 50% share, or we remove the unit at no cost to you.

The Free Assessment ## What you get for free, with no obligation. ![CHEP heating efficiency engineer using a thermal imaging camera to survey a commercial boiler plant room.](/assets/engineer-assessment-bNRcXiwN.webp) A CHEP engineer surveying a commercial plant room. Every assessment is on-site, engineer-led and free of charge. - Site visit by a qualified heating engineer Visual inspection of plant room, system age and condition assessment, dissolved gas indication test where access allows. - 12-month consumption baseline Analysis of your last 12 months of meter data to establish the verified baseline that any savings calculation will reference. - Site-specific savings projection A forecast of the annual saving range your site can realistically achieve, based on system characteristics and consumption profile. - Written proposal and contract draft If your site qualifies, you receive a one-page proposal and the EPC contract for review by your finance team or solicitor. - No obligation to proceed You can decline at any stage. The site visit, baseline analysis, and projection are yours to keep. Frequently Asked Questions ## The questions Estates and FD teams ask first. ### What does the programme actually cost the business? Nothing upfront. Nothing at install. Nothing if your bills do not fall. We invoice only against verified savings, and only for our 50% share. If your bills go up due to colder weather or a tariff change, the methodology degree-day-adjusts the comparison so you are not penalised. ### How does this fit with our ESOS Phase 4 reporting? The unit reduces gas consumption and carbon emissions by approximately 20%. Our monitoring methodology produces verified pre/post consumption data, suitable for inclusion as an implemented energy efficiency action under ESOS reporting and aligned to ISO 50001 documentation requirements. ### How does it interact with our existing BMS? The unit is hydraulically inline and does not require BMS integration to operate. Where you have an open BMS, our monitoring kit can feed data into it for unified reporting. Where it is closed, our portal carries verified consumption data independently. ### How long is the agreement and what happens at the end? A five-year shared-savings term. The VorteXtract unit is leased to the building for the duration of the contract, not sold. At the end of year five the building owner has two options: renew the agreement on agreed terms and continue receiving the 50% share of verified savings, or we remove the unit at no cost to the operator. Specific terms are set in the EPC contract. ### What about multi-tenant buildings or leased estates? The programme is most cleanly run where the freeholder or head leaseholder pays the heating bill. For sub-metered tenant buildings we work with the landlord on either common-area heating (lobbies, corridors, common plant) or a single-tenant arrangement. We assess fit during the free assessment. ### Who is CHEP and how is this funded? The Commercial Heating Efficiency Programme is operated by an independent commercial entity. We are not a government scheme, statutory body, or public authority. The programme is privately funded and recovers cost solely from the share of savings generated post-install.
